LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 579,018, dated March16, 1897.

Application filed February 19, 1896. Serial No. 579,907. (No model.)

To all whom it' may concern,.-

Be it known that we, WILLIAM WALLACE SMITH and JACOB MILnoY'IseRIe.,citizens of the United States, residing at Traverse City, in the countyof Grand Traverse and State of Michigan, have invented a new and usefulLamp-Burner, of which the following is a speciiication.

This invention relates to certain new and useful improvements inlamp-burners, and has for its obj ect to combine therewith means forextinguishing the light and trimmingthe wick, such provisions beingconstructed with especial reference to being applied to any form, style,or pattern of lamp-burner without necessitating a change in theiroutline.

One of the principal features is to obviate choking the air-duct whentrimming the wick by precluding the entrance of the charred wick orcrust into the open end thereof, which is the chief source of annoyance'in lampburners equipped with wick-trimmin g devices.

A further object of the improvement is to locate the combinedextinguisher and trimmer so as to insure a smooth and clean cut, thesame as attained by the use of snuifers and scissors.

The invention consists in certain details of construction and novelcombinations of the parts which hereinafter will be more particularlyset forth, illustrated, and claimed.

In the drawings, Figure l is a perspective view of a lamp-burner havingthe invention applied. Fig. 2 is a detail view of the base or frame,having the gallery and cone removed. Fig. 3 is a detail view of theinvention disassociated from the burner.

Corresponding and like parts are referred to in the followingdescription and designated in the figures of the accompanying drawingsby the same reference-characters.

The base 1 of the lamp-burner is formed with a threaded portion 2 toscrew into the neck of a fount or reservoir and with radial arms 3, towhich the gallery 4t is secured. The lamp-shade holders 5 are attachedto the base and correspond in position with the ra- The Wick-tube 6 mayhave any desired form, and is provided at one side with the iiattenedair-duct 7, of usual formation.V

The gallery 4. is perforated on its top side in the usual way and issupplied with the cone S to regulate the draft and direct the sameproperly to the wick when the same is lighted.

A sleeve 9 is removably tted upon the wick-tube and has a slit l0 in oneside to receive that portion of the air-duct connecting the same withthe wick-tube, and this sleeve is formed at one edge with a verticalbearing 1l in which is j ournaled the wire forming the combinedextinguisher and trimmer. The sleeve conforms to the outline of thewicktube, and as the latter is generally flat the said sleeve willappear flattened and is of such size as to fit snugly upon thewick-tube, so as to resist displacement by slight pressure.

The wire l2 is journaled between its ends in the vertical bearing ll,and its upper projecting portion is flattened and sharpened on one edgeand bent so as to operate over the end of the sleeve 9 and act inopposition thereto to trim the wick by removing the crust or charredportion. The flattened portion 13 of the wire l2 is of a width to extendover the sleeve 9, so as to extinguish the light when required. Thelower Aportion of the wire 12 is bent outwardly, forming a handle 14,which extends beneath the gallery et and is adapted to be reached whenit is required to trim the wick or extinguish the light.

The parts are disposed so that the combined extinguisher and trimmer 13will normally stand out of the way of the wick-tube, so as not tointerfere with the light, and when actuated will actin opposition to thestraight side of the sleeve 9, against which the wick will obtain auniform bearing throughout its width,` thereby enabling a smooth andclean cut being had,whereby a clear flame and light are obtained.Moreoveigthe trimm er operates across and away from the air-duct whentrimming the wick and the crust or charred par ticles of the wick aredropped on that side of the wick-tube remote from the air-duct. Hencethe latter is not liable to become choked as a result of trimming orextinguishing the light.

A spring is employed to hold the wick-trimmer out of the path of thewick-tube and to return it to a normal position when released afterbeing moved either to extinguish the ICO light or trim the Wick. Asshown, this spring 15 is formed of Wire curved in its length and havinghooks 16 and 17 at its ends, one of the hooks, as 16, engaging with theouter end of the handle 14 and the other hook 17 engaging with one ofthe radial arms 3. This spring is located beneath the gallery and isreadily accessible to be placed in position or to be removed, asrequired.

By having the Wire 12 journaledat one edge of the Wick-tube the trimmer13 Will operate by a shearing action and remove the crust and charredWick by a smooth and clean cut, and the said Wire Will obtain a iirm andstrong support in its bearing.

From the foregoing it will be seen that the invention partakes of thenature of an attachment and can be applied to lamp-burners withoutnecessitating any altering or reconstruction thereof, and it Will beunderstood that in providing the attachment for the various makes andsizes of lamp-burners various changes in the form, proportion, and theminor details of construction may be resorted to Without departing fromthe principle or sacrilicing any of the advantages of the invention.

Having thus described the invention, what is claimed as new is- 1. Incombination, a lamp-burner having an air-duct at one side, a sleeveadapted t0 be fitted upon the Wick-tube and having a slit in one side toreceive the connecting portion between the air-duct and Wick-tube, andformed at one edge With a vertical bearing, and a Wick-trimmer journaledin the said bearing of the sleeve and adapted to operate over the latterin opposition to its straight side, and formed With an operating-handleextending Within convenient reach, substantially as set Jforth.

2. The combination with a lamp-burner, of a sleeve adapted to be iittedupon the Wicktube and having a portion bent to provide a verticalbearing at one edge, a Wire journaled in the said bearing and having itsend p0rtions bent, the lower bent end forming a handle and the upperbent end being flattened and sharpened to provide a Wick-trimmer andextinguisher, and a spring for normally holding the Wick-trimmer awayfrom the Wicktube, substantially as shown and described.

In testimony that We claim the foregoing as our own We have heretoatlixed our signatures in the presence of tWo Witnesses.
